## Architecture Integration
|
|
|
|
### MCP Integration Points
|
|
|
|
All consensus agents integrate with the MCP (Model Context Protocol) coordination system:
|
|
|
|
```javascript
|
|
// Memory coordination for persistent state
|
|
await this.mcpTools.memory_usage({
|
|
action: 'store',
|
|
key: 'consensus_state',
|
|
value: JSON.stringify(consensusData),
|
|
namespace: 'distributed_consensus'
|
|
});
|
|
|
|
// Performance monitoring
|
|
await this.mcpTools.metrics_collect({
|
|
components: ['consensus_latency', 'throughput', 'fault_tolerance']
|
|
});
|
|
|
|
// Task orchestration
|
|
await this.mcpTools.task_orchestrate({
|
|
task: 'consensus_round',
|
|
strategy: 'parallel',
|
|
priority: 'high'
|
|
});
|
|
```
|
|
|
|
### Swarm Coordination
|
|
|
|
Agents coordinate with the broader swarm infrastructure:
|
|
|
|
- **Node Discovery**: Integration with swarm node discovery mechanisms
|
|
- **Health Monitoring**: Consensus participation in distributed health checks
|
|
- **Load Balancing**: Dynamic load distribution across consensus participants
|
|
- **Fault Recovery**: Coordinated recovery from node and network failures
|
|
|
|
## Usage Patterns
|
|
|
|
### Basic Consensus Setup
|
|
|
|
```javascript
|
|
// Initialize Byzantine consensus for high-security scenarios
|
|
const byzantineConsensus = new ByzantineConsensusCoordinator('node-1', 7, 2);
|
|
await byzantineConsensus.initializeNode();
|
|
|
|
// Initialize Raft for leader-based coordination
|
|
const raftConsensus = new RaftConsensusManager('node-1', ['node-1', 'node-2', 'node-3']);
|
|
await raftConsensus.initialize();
|
|
|
|
// Initialize Gossip for scalable information dissemination
|
|
const gossipCoordinator = new GossipProtocolCoordinator('node-1', ['seed-1', 'seed-2']);
|
|
await gossipCoordinator.initialize();
|
|
```
|
|
|
|
### Security-Enhanced Consensus
|
|
|
|
```javascript
|
|
// Add security layer to consensus protocols
|
|
const securityManager = new SecurityManager();
|
|
await securityManager.generateDistributedKeys(participants, threshold);
|
|
|
|
const secureConsensus = new SecureConsensusWrapper(
|
|
byzantineConsensus,
|
|
securityManager
|
|
);
|
|
```
|
|
|
|
### Performance Optimization
|
|
|
|
```javascript
|
|
// Benchmark and optimize consensus performance
|
|
const benchmarker = new ConsensusPerformanceBenchmarker();
|
|
const results = await benchmarker.runComprehensiveBenchmarks(
|
|
['byzantine', 'raft', 'gossip'],
|
|
scenarios
|
|
);
|
|
|
|
// Apply adaptive optimizations
|
|
const optimizer = new AdaptiveOptimizer();
|
|
await optimizer.optimizeBasedOnResults(results);
|
|
```
|
|
|
|
### State Synchronization
|
|
|
|
```javascript
|
|
// Set up CRDT-based state synchronization
|
|
const crdtSynchronizer = new CRDTSynchronizer('node-1', replicationGroup);
|
|
const counter = crdtSynchronizer.registerCRDT('request_counter', 'G_COUNTER');
|
|
const userSet = crdtSynchronizer.registerCRDT('active_users', 'OR_SET');
|
|
|
|
await crdtSynchronizer.synchronize();
